The Sexy Technique is simply a Transformation Technique used to transform the user into a beautiful, nude woman (or a woman in a bathing suit, as seen in episode 177 and the Naruto video games). Naruto uses it to distract his instructors, sometimes leading to an exaggerated nosebleed by the victim, and it is indeed annoyingly effective; even the Third Hokage swooned when Naruto used it on him. Naruto was forced to use this jutsu in order to receive training from Jiraiya and has also used it to get Jiraiya's attention if he was slacking off. A variant of this technique is the Harem Technique, which uses varying numbers of shadow clones in combination with the technique to produce multiple clones of a nude women. Naruto teaches the Sexy Technique to Konohamaru in episode 2, who in turn taught it to Moegi and Udon. He has stated he has improved the technique in the second series, but every time before he shows it off Sakura punches him.
